To all whom, it may concern;

Be it known that I, EDWARD PARUSZEWSKI, a subject of the German Emperor,residing at Kottbus, in the German Empire, have invent ed certain newand useful Improvements in Looms for WVeaving Tufted Fabrics, of whichthe following is a specification.

This invention relates to looms for weaving tufted fabrics.

One object of the invention is to provide a loom of this type in which aplurality of pattern-forming mechanisms, each comprising yarn selecting,feeding, cutting, and knotting devices, may be operated from a singlekeyboard.

The invention also contemplates the provision of improved means foroperating each and all of said mechanisms from the keyboard.

It is also an object of the invention to provide a loom in which theseveral patternforming mechanisms embodying the instrumentalitiesindicated above are simultaneously shifted transversely of the warp bymechanism which is actuated by each keg.

The invention further purposes to furnish an improved pattern-formingmechanismviz., mechanism for selecting and knotting the yarn for use inlooms of the type indicated.

With these objects in view the invention consists in the novel featuresand combinations of parts to be hereinafter described, and linallrecited in the claims.

In the accompanying drawings, in which similar reference charactersdenote the same parts throughout the several views, Figures 1 and 1 inconjunction show a plan view of the improved loom in which the knottingdevices of the different pattern-forming mechanisms are omitted for thesake of clearness, a portion of the keyboard being broken away. Fig. 2is a side elevation, partly in section. Figs. 3 and 4 are two differentelevations of the knotting mechanism, showing the parts indifferentpositions. Fig. 5 is a detail of the knotting mechanism; andFigs. 6 and 7 are detail pers iective views of the knotting mechanism,showing the knot-forming grippers separated from their actuatingdevices.

A number of pattern-forming mechanisms a for knotting or tying the loopsof i'ard are arranged side by side transversely of the warp-threads It,said mechanisms corresponding in number to the patterns in the repeat ofthe fabric. Each of such mechanisms comprises a set of yarn-holdingreels and all the instrumentalities necessary to knot the desiredpattern from the yarn thus held, as will be presently explained, andsaid reels and other instrumentalities of each mechanism are mounted ona suitable frame movable transversely of the warp-threads by means ofrollers which move along a track supported on the loom-frame, asindicated, and by means of sleeves 54, threaded on a threaded shaft 53,as shown in Figs. 1 and 2.

In the figures just mentioned an entire pattcrn-knotting mechanism isshown, together with part of a second one, it being understood, however,that the number of such mechanisms used in the loom is theoreticallyunlimited. All the mechanisms a are actua ted simultaneously by one andthe same keyboard w in order in each mechanism to select the color ofyarn to be used for the time being and to feed it to the knottingdevices. The yarns of different colors are wound upon reels or cops 22in each mechanism and are led thence to 'arn-presenting disks 17, havingperipheral openings through which the strands of yarn protrude, beingheld lightly in position by means of spring-actuated pressers b in sucha manner that the; can be readily drawn out and unwound from the cops22.

It is necessary that by the pressure upon one of the keys of thekeyboard 10 all of the yarn-presenting disks 1? of the different pattern-forming mechanisms shall be simultaneously so adjusted as topresent the yarn of the required color to the feeding nteans, by whichthe sante is carried to the knotting devices of each mechanism a. In thearrangement shown in the drawings the feeding device is designed to actupon the yarn held at the lowermost part of the disk 17. Said feedingireans is illustrated as a gripper 2, by means of which a certain lengthof yarn is drawn out of the disk 17 in a manner to be presentlydescribed in order to be looped and knotted about two of thewarp-threads. The adjustment of all the disks 17 for this purpose iseffected from the keyboard 10, as follows: On pressing down a key 1(each of which is advantageously indicated by means of a piece of yarnof a color which is selected by the disk 17 upon the depression of thekey) an elbow-lever 2, moved by the key, and a slide 3, actuated by saidelbow-lever, cause the upper end of an upright rack 4 to be movedrearwardly against the action of a spring 20,

the rack, which is guided in vertical direction 1 eratively connectedwith the shaft by inby a roller 5, being thus partly rotated about agear-wheel 6, with which it engages. Each rack is provided at its lowerportion with a nose or catch 7, said noses being arranged at differentheights on the several racks. The parts 1, 2, 3, 4, 6, and 20, as shownin Fig. 1, are of a number corresponding to the number of yarn-colors.The gear-wheels 6 are all mounted loosely on a common shaft B and eachis fixed to a disk 10, provided with a peripheral lug 9, as shown inFig. 2. A bar 11 is adapted to rock the shaft of the gear-wheels 6 bymeans of perforated ears which are keyed to said shaft at its ends, saidbar 11 extending completely across the keyboard and normally abuttingagainst the lugs 9 of the several disks 10, as shown in Fig. In front ofthe racks 4 a knife-like bar 8 is continuously reciprocated to a uniformextent in a vertical direction by means of the driv ing-shaft of themachine, with which it is con nected by suitable transmission devices,such as those indicated.

When one of the keys is depressed, the corresponding rack is by the above-described arrangement swung forward at its lower end, so that thebar 8, according to the position of the nose 7 with respect thereto,will sooner or later engage said nose during its upward movement andwill as a consequence elevate the corresponding rack to a greater orless degree, thereby causing the corresponding gearwheel 6, with whichit engages, to be turned to a corresponding extent. The lug 9 of thedisk 10, which is adjacent such gear-wheel, is thereby made to rock thebar 11 to the same extent as the gear-wheel, such extent being, asbefore stated, dependent upon the height of the nose or projection 7 onthe corresponding rack. The bar 11 actuates, through the shaft B achain-wheel 12, which is fixed to said shaft and from which partialrotation is transmitted to the yarn-presenting device 17 by means of achain 13, chainwheel 14, shaft 15, and gear-wheel 16, which latter isengaged with a toothed ring on the disk 17, so that this disk is therebyset in such position that the yarn of the desired color arrives at thelowermost point opposite the tongs or gripper z. The parts are thus heldin adjusted position so lon as the corresponding key is held down, thisbeing insured by a notch 18 in the rack 4, which catches upon a fixedbar 19, suitably mounted in the loom-frame. Therefore so long as the keyis not released the disk 17 maintains its position and loops of thesame-colored yarn will be continuously cut and knotted. When the key isreleased, spring 20 pushes the rack 4 away from the bar 19, and a weight21, acting upon the shaft 15, carries the wheels and disk 17 back intoinitial position. All of the yarnpresenting devices 17 of the mechanisms(1 are operated in the same manner, being opin Figs. 3 and 4.

strumentalities similar to those just described, so that upon theactuation of said shaft by one of the keys the same color of yarn willbe presented by each of the presenting devices.

After the knotting of each loop each mechanism a must be shiftedtransversely of the warp-threads k for a distance corresponding to twoof said threads, as the knot is formed about two tlneadsf-This lateralshifting is also effected by the depression of the keys, and hence willbe described before the knotting devices. A bar 23 extends transverselyunder all the keys, as shown in Figs. 1 and 2, so that upon thedepression of a key 1 said bar is made to move a lever 24, 'so that bymeans of a lever-25 and slide 26, arranged at one end of the keyboard,the last rack 27 is moved in the same manner as was described withreference to the racks 4, serving for the selection of the color. Bymeans of the rack 27 a gear-wheel 28 is rotated, to which wheel is fixeda crank-disk connected by a pin 29 to a connecting-rod 30, as shown inFigs. 1. and 2. The rod 30 is connected to a lever 31, by means of whichone member 34 of a toothed clutch K is made to engage the other member33, fixed on the driving-shaft 32, when the gear-wheel 28 is turned bythe depression of a key in the manner described. By this means the shaft35 is coupled to the shaft 32, and the resulting rotary motion of theformer shaft is transmitted, by means of bevel-gears 36 and 37,chain-wheel 38, chain 39, and chain-wheel 40, to the shaft 41, whichextends transversely of the warp-threads at the upper portion of theloom above the several pattern-forming mechanisms a. By means of theshaft 41 a reciprocating motion is imparted to a ratchet-pawl 51 bymeans of a crank-disk and connecting-rod 49, the pawl being thereby madeto turn the ratchetwheel 52 through a certain distance at each forwardmotion. The ratchet-wheel 52 is fixed upon the threaded guide-spindle53, on which the threaded sleeves 54, fixed to the frames of themechanisms a, are mounted, as hereinbefore described. The ratchet-gear,the pawl 51 of which is formed double in order to'operate in eitherdirection, serves to shift the mechanisms at to the extent of twowarp-threads in the direction of the weft after the formation of eachknot.

From the shaft 41 the shafts 47 of the pattern-forming mechanismsreceive their rotary motion by means of the bevel-gears 42 and 43, shaft44, and bevel-gears 45 and 46. On each shaft 47 are arranged the cams bywhich the knotting devices of each patternforming mechanism areoperated, as shown Said knotting devices, as shown in Figs. 3, 4, 5, 6,and 7, consist, essentially, of the feed-grippers 2, already mentioned,which draw the end of the yarn from the presenting-disk 17, the shearss, which cut it off, the two cranked loop-forming grippers g and whichseize the ends of the yarn length and pass the same downwardly throughthe warp-threads, so as to include two of the latter, and a middleknottinggripper 772, which seizes the ends of the yarn length whenpassed through such warpthreads draws them up between said threads, anddraws the loop thus formed by a locking motion toward the finished partof the fab- The two loop-forming grippers g g are held in bearings 55and 56 at the upper and lower portions of a rectangular frame 57, whichslides vertically in a guide 88 of the loom-frame. The intermediategripper m is also mounted on the frame 57 and partakes in its verticalreciprocating motion, which is imparted to the same by means of a cam58, fixed on shaft 47, and a rod 59. The action of the frame 57 is suchthat the same remains stationary in its highest position during thefirst quarter-revolution. of the shaft 47, then descends during thesecond quarter revolution, then remains stationary in its lowermostposition during the third quarterrevolution, and finally rises againduring the last quarter-revelution of said. shaft. \Vhen the frame is ata standstill in the high ist position, the grippers g g are in theposition shown in Fig. 3, in which the middle gripper 'm is, however,supposed to be open. The feeding-gripper 2 is also open, and the shearss are at their greatest distance from the yarn ends While the frame 57is still stationary, the rotation of shaft 47 causes, by means of thecam 60, rod 61, and elbow-lever 62, the gripper 2, which slides on aslide-bar 63 in a guide 64 of the loom-frame, to be pushed toward theyarn end f. 'loward the end of this movement the catch 65, which holdsthe feerling-gripper open, bears against the fixed pin 66, whereby themovable part or linger 67 of said. gripper is released, and the gripperthen closed by the action of the spring 68. The gripper 2 thus grips theyarn end and draws it during the subsequent backward motion between thegrippers g At the end of the return stroke aft r the knot-forminggrippers g 9 have seized the yarn the inclined. end of the part 67 ofthe feeding-gripper strikes against a fixed pin 67, whereby said gripperis again opened and is then held open by engagement with thespring-actuated catch 65.

During the movement of the gripper 2 a slotted slide 69, which isactuated by the shaft 47 by means of a cam 7 O, has seize the pin 7]. ofa plate 72, Figs. 3, 4, and 5, which slides in a guide 7 3 of the frame57 and carries said plate downwardly. In this movement a pin 7 4 of saidplate 7 2 bears againit the incline of catches 76, which are thusdisengaged from pin 77 of the movable part of the grippers g so as torelease said grippers. As a consequence said grippers close under theaction of spring 79 and some the yarn laterally in the manner indicatedin Fig 6. At this moment the gripper 2 is opened in the manner abovedescribed.

As soon as the grippers g and g have seized the yarn near its ends andthe feeding-gripper 2 is opened the shears s are moved in their guide 83toward the yarn and back again therefrom by means of a cam 80, red 81,an-l elbow-lever 82, as shown in 3. During this movement a fixed pin 84slides .in the angular lo t 85 of the shears arms 86, and thereby theshears are opened during the forward motion an closed during thebackward motion, so that the yarn is thereby cut off in front of thedisk 17.

During the second. quarter-revolution of the shaft 47 the frame 57,together with the grippers g, g, and m, moves downwardly. During thismotion a pin 90, fixed to a bracket 89 of the framing, slides in thehelical groove 91. of a cylinder 92, connected to the upper portion ofthe gripper g. The gripper 9 thus d escribes a semirevolutien, which istransmit ted, through gears 93 and 94, to the gripper g wnich movementis indicated in Fig. 5 by dotted arrows. In consequence of the crankform of the grippers at their lower ends said ends do not rotate upontheir axes, but describe an are about the longitudinal axes of the upperon s of the grippers, so that the gripping ends turn in oppositedirections an i bring together the ends of the yarn length, so as to farm a loop, as shown in Fig 7. This rotation of the loop-f, -minggrippers is already completed at the first half of the downwardmoven'ient, so that the gripper ends and the yarn length are alreadycisposed at a height of about ten i'nillimeters above the warpthrea l inthe position shown in Fig. 7. During this rotation of the loop-forminggrippers a pin 95 cl the intermediate gripper m slides in an obliqueslot 96 of the frame 57. By this means the intermeiate gripper wereceives a rocking motion at right angles to the face of the (tick 17,with the pin 97 of the guide-r; d 98 as a pivot, until the en s of themid le gri per pass between the two loopfnwning grippers g 9*, as shownin Fig. 7. During the following second half of the downward motion ofthe frame 57 the grippers g and together with the bent yarn length, pare through the warp-threads in the manner shown in Fig. 4, therebylaying the middle part of the length over two warp-threade and takingthe two end; of tl'iese warp-threads downwardly. As the spring 99 yieldsduring the downward motion of the frame 57 the intermediate gripper malso descends through l the warptln'eads, passing between the twowarp-th earls over which the lateral grippers I liy the yarn length, asshown in Fig. 4. Durl ing the third quarter-revolution the frame 57,

with three grippers, remains in this lowest position. The pin 71 of theplate 72, which during the downward motion of the frame 57 can slide inthe slot 100 of the slide-piece 69 without altering the relativepcsiticn between said plate 72 and said frame 57, is now seized by theslide 69, which draws the plate 72 upwardly. During this movement theplate 72 strikes against the nose or lug 101 of the catch 102, whichholds open the middle gripper, and in thus disengaging sai catch causessaid middle gripper to be closed by a spring 103, so as to grip the twoyarn en. During the further upward motion the plate 72 strikes againstthe incline 104, Fig. 3, 0f the grippers g and 9 thereby opening thesesomewhat, so that they release the yarn.

During the fourth quarter-revolution of the shaft 47 the frame 57 withthe three grip pers arrives upwarcly, the grippers retaining during thefirst half of the upward motion the samerelative positions, the gripperm drawing the ends of the yarn lengths upwardly, so as to form a knot.Said gripper is drawn upwardly by the spring 99 until the pin 105strikes against the fixed framingpiece 89. As the frame 57 moves stillfarther upward, the pin 95 of the intermediate or middle gripper slidesin the slot 96 of the frame 57, which causes said gripper to swing backinto its original position, thereby bringing the completed yarn loop ortuft close up to the part of the fabric which has already been formed,as shown in Fig. 3. In the meantime the loop-forming grippers turn backinto their original position in moving in openings 111 of the plate 72,which openings have curved surfaces formed eccentrically to the axis ofrotation of said. grippers, so that said grippers are therebycompletelyopened again. In this position they are held by the catches 76. Beforethe abovedescribed operation recommences the middle gripper m is openedagain by means of a pin 106, which is moved upwar ly by means of a cam107 and a rod 108 and which slides against an incline 109 of the movablepart 110 of said. middle gripper, and this is then locked in openposition by means of the spring-actuated catch 102.

The knotting devices of all the patternforming mechanisms (1 aresimultaneously operated in the manner set forth by their connection withthe operating-shaft 41 through the shafts 44 an 47, said. operatingshaft41 being actuated from the keyboard,
